Issue in using Apiary APIs

Hello,

I am able to use the documentation located at https://support.smartbear.com/zephyr-squad-cloud/docs/test-automation/api.html
to create JWT token and then create/update automation tasks. The APIs on this page use the https://prod-vortexapi.zephyr4jiracloud.com URL.
But I also want to use some specific APIs located at https://zephyrsquad.docs.apiary.io/ which use a different URL (https://prod-api.zephyr4jiracloud.com/connect/)
I want to use APIs to:
# Create a cycle
# Create a folder for above generated cycle
# Create execution for generated cycle ID
# Add tests to cycle
# Add tests to folder

Can you please guide me on how I can use both APIs at the same time using the same/different endpoint URL and JWT token? Currently since the endpoint URLs are different, some APIs are not available on the other URL and I am facing issues in JWT token generation for https://prod-api.zephyr4jiracloud.com/connect/

Two different sets of documentation are confusing me. Kindly guide me.

Thank you,
Harshad
